   Sorry, I should have been more clear. This will only work on
the server side for the particular object. Accessing the object
id from clients breaks the transparency of object references and
is outside the CORBA object model.

   Perhaps if you gave us an idea of you are using the object id
we could suggest alternative designs which would work.

=>I'm not sure but perhaps the get_interface () can do this for me.

   No, this only gives you access to the TypeCode of the object
in the Interface Repository, if you've set one up. It won't tell
you anything about the object's identity.
